Whiskey or Coffee?

Jack and his Japanese friend, Norie, are on their way home from school. (N=Norie; J=Jack)
N : What a hard day I had at school! I feel like having a coffee or something.
J : Me, too.
N : Let's go to Rick's Coffee Shop.
J : That sounds good. (They are at the coffee shop.)
N : What kind of coffee do you like?
J : I feel like having an Irish coffee.
N : OK. I'll have the same. (After two cups Norie is drunk.) Why am I feeling tipsy?
J : There's whiskey in Irish coffee, you know.
N : Why didn't you tell me? Boy, it can be dangerous to have a simple cup of coffee with an American.

杰克和他的日本朋友则惠正在从学校返家的途中。
则惠:今天在学校过得好辛苦!我想要喝杯咖啡或什么的。
杰克:我也是。
则惠:那我们去瑞克咖啡馆吧。
杰克:听起来不错。(他们在咖啡馆里面。)
则惠:你喜欢喝哪种咖啡?
杰克:我想来杯爱尔兰咖啡。
则惠:好吧。我也要一样的。(喝完两杯后则惠就醉了。)为什么我觉得有点醉?
杰克:你知道的, 爱尔兰咖啡里加有威士忌。
则惠:你为什么没跟我讲呢?天啊, 连和美国人喝杯咖啡都可能会有危险。
